This fixes the second of two problems i've been having. The first
of which i'm rather unsure what the right solution is, so Keir should
probably also have a look at it:

My machine page faults during the memory "Scrubbing"; the heap pages
are "guarded" until allocated and now map_domain_mem() doesn't do
anything except phys_to_virt(), thus no present bit and page fault
when clean_page() gets called.
